Programming Hardwired Zones
Each zone must be programmed into the system using the ✱ 56 Zone Programming Mode or
✱ 58 Expert Programming Mode, which assigns characteristics that define the way the system
responds to faults on that zone. Refer to the ZONE RESPONSE TYPE DEFINITIONS and
ZONE PROGRAMMING sections for specific instructions on programming hardwired zones.
